Abstract: Twenty-one digit-sucker children aged 4-12 old years participated in the assessment of a new reminder therapy technique called "long sleeve sleeping gown ". The result of this study indicated that fifteen children (71.4%) out of 21 were able to stop digit-sucking habits after the application of long sleeve's gown during child's bedtime for 6 weeks. The children who failed to cease this digit-sucking habit (28.6%) were found to not accept to complete the trial period or their mothers thought that they were too young to stop the habit. Among the success group no child was reported to return to digit-sucking 3 months after implementation of long sleeves gown.
